Step-by-step explanation:

Note the common difference d between consecutive terms of the sequence

8 - 6 = 10 - 8 = 2

This indicates that the sequence is arithmetic with n th term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 6 and d = 2, thus

[tex]a_{n}[/tex] = 6 + 2(n - 1) = 6 + 2n - 2 = 2n + 4 ← explicit formula

Hence

[tex]a_{130}[/tex] = (2 × 130) + 4 = 260 + 4 = 264

Step-by-step explanation:

Because of the answers that you gave I'm going to assume the radians were 3pi/4. That would be A, 135 degrees.

If this is the wrong amount of radians please let me know.

The radian measures of the given degree measures are 3π / 4 Rad, π Rad, 3π / 2 Rad and 2π

One radian is the measure of a central angle subtended by an arc that is equal in length to the radius of the circle. When no symbol is used, radians are assumed. When degrees are the unit of angular measure, the symbol "°" is written. Note that the radian is a derived unit in the International System of Units (SI).

Given are some degree measurements, 135° 180° 270° 360°, we need to convert them into radians.

Since, we know that,

1 Rad = 1 Deg × π / 180

Therefore,

1) 135° = 135 × π / 180

= 3π / 4 Rad

2) 180° = 180 × π / 180

= π Rad

3) 270° = 270 × π / 180

= 3π / 2 Rad

4) 360° = 360 × π / 180

= 2π

Hence, the radian measures are 3π / 4 Rad, π Rad, 3π / 2 Rad and 2π

The next higher million is 68 million.

The next lower million is 67 million.

67,492,384 is closer to 67 million than to 68 million.

So the nearest million is 67,000,000 .

To round 67,492,384 to the nearest million, round the millions place up by 1 because the digit to its right is 7.

To round 67,492,384 to the nearest million, we need to consider the digits in the millions place and the digit to its right. In this case, the digit in the millions place is 6, and the digit to its right is 7. Since 7 is greater than or equal to 5, we round the millions place up by 1. Therefore, 67,492,384 rounded to the nearest million is 68,000,000.

The ratio of Han's measurements and Tyler's measurements corresponds with polenta measurement

Given:

Polenta:

Cups of water = 5

Cornmeal = 2

Ratio of cups of water to cornmeal = 5 : 2

= 5/2

= 2.5

Han:

Cups of water = 3

Cornmeal = 1 1/5

= 6/5

Ratio of cups of water to cornmeal = 3 : 6/5

= 3 ÷ 6/5

= 3 × 5/6

= 15/6

= 2.5

Tyler:

Cups of water = 7 1/2

= 15/2

Cornmeal = 3

Ratio of cups of water to cornmeal = 15/2 : 3

= 15/2 × 1/3

= 15/6

= 2.5

Therefore, the ratio of Han's measurements and Tyler's measurements corresponds with polenta measurement.

Final answer:

The question involves mathematical ratios to determine the correct proportions for a polenta recipe. By setting up proper proportions, we confirm that Han's and Tyler's calculations for the amount of cornmeal and water needed are correct.

Explanation:

The question discusses proportions used in a recipe which relates to mathematical ratios. Han and Tyler are trying to determine how much cornmeal and water they need for polenta based on a recipe that calls for a specific ratio of these ingredients. To solve this, we must set up a proportion that maintains the constant ratio given by the recipe.

For Han's statement, since the recipe calls for 5 cups of water for every 2 cups of cornmeal, we can set up the following proportion:

5 cups water / 2 cups cornmeal = 3 cups water / x cups cornmeal

Multiply across the equal fractions (5 * x = 2 * 3)

x = 6/5 or 1.2 cups cornmeal, which confirms Han's statement as correct.

For Tyler's statement, using the same ratio:

2 cups cornmeal / 5 cups water = 3 cups cornmeal / x cups water

Multiply across the equal fractions (5 * 3 = 2 * x)

x = 15/2 or 7.5 cups water, which confirms Tyler's statement as correct as well.

The present age of Michael is 33 years .

Step-by-step explanation:

Given as :

Michael is 17 years older than Brandon

And 17 years ago the age of Michael was 4 times as old as Brandon

Now,

Let the age of Michael = M years

And The age of Brandon = B years

So , According to question

M = B + 12                             .........A

And ( M - 17 ) = 4 × ( B - 17 )

Or, M - 17 = 4 B - 68

Or, 4 B - M = 68 - 17

or, 4 B - M = 51               ...........B

Solving Eq A and B

I.e 4 B - ( B + 12 )= 51

or, 4 B - B = 51 + 12

or, 3 B = 63

∴  B = [tex]\frac{63}{3}[/tex]

I.e B = 21 years

So, Now the age of Brandon = B = 21 years

Put the value of B in eq A

So, M = B + 12

∴   M = 21 + 12

I.e M = 33 years

So, Now the age of Michael = M = 33 years

Hence The present age of Michael is 33 years . Answer

Answer:

The aquarium can be made by 83 sq. ft. of glass.

Step-by-step explanation:

The public library aquarium is in the shape of a hollow cuboid.

The dimensions of the hollow cuboid are 6 ft by 2.5 ft. by 4 ft.

Now, the total surface area of the aquarium will be given by 2(LW + WH + HL)

Where, L = length = 6 ft, W = width = 2.5 ft and H = height = 4 ft.

If the top of the aquarium is open, then the total surface area will be

= 2(WH + HL) + LW

= 2(2.5 × 4 + 4 × 6) + 6 × 2.5

= 83 sq. ft.

Therefore, the aquarium can be made by 83 sq. ft. of glass. (Answer)

To calculate the square feet of glass used for the aquarium, we find the total surface area of the rectangular prism excluding the top. The total surface area is 83 square feet.

To find out how many square feet of glass were used to build the aquarium, we need to calculate the surface area of the rectangular prism minus the top since it is open.

The surface area of a rectangular prism is given by the formula:

Surface Area = 2lw + 2lh + 2wh

where l is the length, w is the width, and h is the height.

Given the dimensions of the aquarium:

First, we calculate the areas of the sides:

Total surface area excluding the top is:

Total Surface Area = 2lw + 2lh + 2wh - (length * width)

Total Surface Area = 30 + 48 + 20 - (6 * 2.5) = 98 - 15 = 83 square feet

So, 83 square feet of glass were used to build the aquarium.

The amount of money in Victoria's account at the end of n-th year will be,

$ [tex] (965 \times (1.02)^{(n -1)} - 765)[/tex]

Step-by-step explanation:

The amount of money in Victoria's account at the end of n-th year will be,

$ [tex](200\times (1.02)^{(n-1)} + 15 \times ((1.02)^{(n-1)} + (1.02)^{(n -2)} + (1.02)^{(n-3)} + ........ + (1.02)))[/tex]

= $ [tex](200 \times (1.02)^{(n -1)} + 15 \times \frac{1.02 \times ((1.02)^{(n-1)} - 1)}{0.02})[/tex]

= $ [tex](200 \times (1.02)^{(n -1)} + 15 \times 51 \times ((1.02)^{(n-1)} - 1))[/tex]

= $ [tex] (965 \times (1.02)^{(n -1)} - 765)[/tex]

Since, the interest is compounded over that $ 200 (which was there in the account at the end of 1st year) for (n-1) years and for (n-1) years, (n-2) years, (n -3) years, ...... 1 year respectively over those $ 15 which are deposited in the account at the end of 1 , 2, 3, ...... (n-1) years.

Answer:

[tex]a_{n}=\left [ a\left ( n-1 \right )+15 \right ]*1.02\\[/tex]

Step-by-step explanation:

1) A Recursive formula always makes reference to the previous term, written as a function.

2) From $200 to $215 there was a 7.5% growth, so since the question states that from the beginning of the second year there will be a regular growth.

3) Since it is 2% of interest compounded annually q=1+ 0.02.

[tex]A=215(1+\frac{0.02}{1})^{1}\\A=219.3[/tex]

Or simply

215*1.02=219.3

4) We can write a Recursive formula this way:

[tex]a(n)=215[/tex]

[tex]a(n)=a(n-1)(1.02)[/tex]

5) But since we have a pattern, She will deposit $15 yearly then we must make a little adjustment then add $15. to that. Considering the first term to be 200

[tex]a_{n}=\left [ a\left ( n-1 \right )+15 \right ]*1.02\\a_{1}=200[/tex]

Answer:

The needed quadratic equation is : [tex]p(x) = x^2 -3x + 10[/tex]

Step-by-step explanation:

The given equation is of the form [tex]p(x) = ax^2 + bx + c[/tex]

The given solutions of the equations are:

x = 3 +i, x = 3 - i

Now, if x = a is the zero of the polynomial p(x)

⇒(x -a ) is the root of the given polynomial.

⇒ (x - ( 3+i)) and (x - ( 3+i)) are the given roots for p(x)

P(X) = PRODUCT OF ALL ROOTS

⇒ p(x) = (x - ( 3+i))(x - ( 3-i))  = ( x-3 -i)(x -3+i)

Now, [tex](a-b)(a +b) = a^2 - b^2\\\implies ( (x-3)-i)((x-3)+i) = (x-3)^2 - (i)^2 = x^2 +9 - 3x -(-1)\\= x^2 +10 - 3x\\\implies p(x) = x^2- 3x + 10[/tex]

Hence, the needed quadratic equation is : [tex]p(x) = x^2 -3x + 10[/tex]
